transparency and accountability on the part
of government departments. We also helped
Canadians better understand the implications
of security measures on their privacy.
At the same time, we have supported and
informed the work of policymakers and
Parliamentarians by identifying privacy
concerns with respect to proposed public safety
legislation. We believe our input was valued
and carefully considered, and ultimately led
to better informed decision-making.
In most cases, we believe the end result for
Canadians has been a more privacy respectful
approach to public safety issues.
Here are some examples of our work:
A Matter of Trust
In 2010, we published a reference document
entitled
A Matter of Trust: Integrating Privacy
and Public Safety in the 21
st
Century
.
This publication lays out an analytical
framework to guide Parliamentarians, policy-
makers and program designers to be able to
incorporate both public safety and privacy.
It begins with the underlying premises
and principles, then sets out the checks
and balances that ought to inform any
new initiative that could infringe on
people’s privacy.
Before authorities unveil a new measure to
boost public safety at the possible expense
of privacy, we encourage them to ask
themselves four questions: Is the initiative
truly necessary? Would it be effective for
the desired purpose? Would any resulting
infringement on privacy be proportionate to
the expected benefit derived? Are there any
other less intrusive alternatives available?
Airport Body Scanners
Most travellers through Canadian airports
are familiar with the whole-body imaging
scanners that can detect non-metallic
weapons, explosives, or other threats to
aviation safety.
Their privacy is better protected as a result
of the consultations that the Canadian Air
Transport Security Authority, or CATSA, had
with our Office.
After reviewing CATSA’s plans as outlined in
a Privacy Impact Assessment, we suggested
a variety of privacy enhancements, which
CATSA adopted.
For example, passengers have the right
to choose a physical pat-down instead
of a scan, and scanners are only used as a
secondary measure, once a specific threat has
been identified. What’s more, the
images are deleted once an official has
confirmed that there is no threat.
In 2011, we conducted an audit and
confirmed that the scanned image cannot be
reproduced and is permanently deleted after
the passenger has left the scanning area. We
